The American Civil Liberties Union of Maine and the Brennan Center for Justice are asking for a federal investigation into alleged voter intimidation during the last election.

The ACLU and the Brennan Center, a non-partisan organization based at New York University School of Law, filed the request with the U.S. Department of Justice's Civil Rights Division on Friday.

The request stems from a November 13th statement by outgoing Maine Republican Chair Charlie Webster that he planned to mail hundreds of postcards to non-residents he suspects voted to see if they're returned. According to Webster, if the cards we returned, it would indicate those voters were not eligible to vote in Maine. Webster later apologized for saying "dozens of black people" unfamiliar to election officials had voted in rural towns November 6.
